  As shown in FIGS. 1, 2 and 6, the main body 43 of each moving member 41 is provided with a lock mechanism 67 for locking the link mechanism 61 at the lock position P1. A plurality of long holes 68 extending along both sides of the screw shaft 38 are formed in the substrate 23 so as to penetrate the substrate 23. Each lock mechanism 67 extends along the axial direction of the rotary shaft 22 through a pair of elongated holes 68 on both sides of each screw shaft 38 and has a pair of support cylinders 69 having a front end fixed to the main body 43, and a support A pair of rods 70 movably inserted into the cylinder 69 are provided.

On the main body 43 of the moving member 41, a stopper 73 that restricts the backward movement of the second link 65 of the link mechanism 61 is formed so as to protrude forward.

  At normal times, as shown in FIGS. 1 and 2, the spring 72 urges the connecting pin 66 of the link mechanism 61 toward the substrate 23 via the rod 70 and the lock lever 71. As a result, the first link 63 and the second link 65 of the link mechanism 61 are urged to rotate toward the substrate 23 around the first support pin 62 and the second support pin 64, respectively. . By engaging the stopper 73 with the second link 65, the axial center of the connecting pin 66 is slightly less than the dead point arranged on the straight line connecting the axial centers of the first support pin 62 and the second support pin 64. In the position arrange | positioned back, it is comprised so that the movement to the back of the 2nd link 65 may be controlled. Hereinafter, this position is referred to as a lock position P1. In the state of the lock position P1, the first link 63 and the second link 65 of the link mechanism 61 are locked so as not to rotate. Therefore, the shaft center of the connecting pin 66 is prevented from moving backward from the lock position P1, and thus the support member 45 of the moving member 41 that supports the split piece 25 is prevented from moving radially inward. ing.

  As shown in FIGS. 2 and 6, the device frame 21 is provided with a lock release mechanism 74 for releasing the lock of the link mechanism 61 by each lock mechanism 67.

  After the winding of the wire W to the groove 58 on the outer periphery of the divided piece 25 is completed, that is, after the formation of the bead ring B is completed, the substrate 23 is stopped at a predetermined position. At this time, the rear end of the rod 70 of the lock mechanism 67 is disposed so as to correspond to the pressing portion 76 of the lock release mechanism 74. In this state, when the cylinder 75 is operated so as to protrude from the piston rod, the rod 70 is pressed forward by the pressing portion 76 as shown in FIG. As a result, the rod 70 moves the connecting pin 66 of the link mechanism 61 in a direction away from the substrate 23 via the lock lever 71 to release from the lock position P1. As a result, the first link 63 and the second link 65 of the link mechanism 61 are released from the locked state, and the support member 45 of the moving member 41 that supports the split piece 25 is moved radially inward, and the bead ring. B separates from the inside of the groove 58.

In this state, when the substrate 23 is rotated in one direction by the rotating shaft 22, the wires W are stacked in the step direction in the state where the wires W are arranged in the column direction in the grooves 58 on the outer periphery of the divided pieces 25. The bead ring B is formed by winding.

  When the substrate 23 is stopped at a predetermined position after the formation of the bead ring B, the rear end of the rod 70 of the lock mechanism 67 is disposed so as to correspond to the pressing portion 76 of the lock release mechanism 74. In this state, when the piston rod of the cylinder 75 of the unlocking mechanism 74 is operated so as to protrude, as shown in FIG. 6, the first link 63 and the second link 65 of the link mechanism 61 are in the locked position P1. The lock is released. As a result, the support member 45 of the moving member 41 that supports the split piece 25 is moved inward in the radial direction, and the bead ring B is detached from the groove 58. Therefore, the bead ring B is easily removed from the divided piece 25.

  When it is necessary to adjust the winding diameter of the bead ring B formed on the divided piece 25, the handle 30 is attached to the attachment portion 28a of the handle shaft 28, and the handle shaft 28 is rotated by operating the handle 30.

  When it is necessary to change the winding width of the bead ring B formed on the divided piece 25, the position of the adjusting portion 56 in the winding portion 52 of the divided piece 25 is adjusted as shown in FIG. . With the plurality of screws 57 loosened, the adjustment portion 56 is moved rearward or forward along the axial direction of the rotation shaft 22 with respect to the main body portion 55. Thereby, the groove width L1 of the groove 58 formed between the main body part 55 and the adjustment part 56 is enlarged or reduced, and the winding width of the bead ring B can be changed.

  For example, when it is necessary to change the cross-sectional shape of the bead ring B formed on the divided piece 25, the winding part 52 is removed from the attachment part 50 of the divided piece 25, and the desired bead ring B is removed. Is replaced with a winding unit 52 configured to form Thereby, the cross-sectional shape of the bead ring B can be changed to a hexagonal shape, for example, as in a second embodiment described later.
